Android中Toast的自定义

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="#000000" >    <Button         android:id="@+id/customToast"        android:layout_height="wrap_content"        android:layout_width="match_parent"        android:text="CustomToast"/>    </RelativeLayout>

这是main.xml，main.xml中的代码很简单就只有一个Button

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:padding="10dp"    android:background="@null" >        <ImageView         android:id="@+id/image"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:layout_marginRight="10dp"/>        <TextView         android:id="@+id/text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textColor="#fff"/></LinearLayout>

这个就是自定义Toast的布局。需要的image和text在Java代码中自定义添加的！

package com.msr.toast;import android.app.Activity;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.ImageView;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends Activity {    private Button customToast;        public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        customToast = (Button)findViewById(R.id.customToast);        customToast.setOnClickListener(new OnClickListener() {                        public void onClick(View v) {                Toast toast = new Toast(MainActivity.this);                LayoutInflater inflater = MainActivity.this.getLayoutInflater();                View toastLayout = inflater.inflate(R.layout.customtoast, null);                TextView text = (TextView)toastLayout.findViewById(R.id.text);                text.setText("You are my angle!");                ImageView image = (ImageView)toastLayout.findViewById(R.id.image);                image.setBackgroundResource(R.drawable.ic_launcher);                toast.setView(toastLayout);                toast.setDuration(Toast.LENGTH_LONG);                toast.show();            }        });    }}

这个就是Java中代码。这个自定义感觉很有必要！特别是在提示什么的时候，如果还是系统自带的有点难看！
